To all whom it may concern Be it known thatI, Josnrrr J. Herenmo- ToN, a citizen of the United States, residing at Philipsburg, in the county of Granite and State of Montana, havejinvented cer-vv tain new and useful Improvements 1n Chuckf Pins, of which the following isa specification, reference being had to the accompany'- ing drawings. f

rfhis invention relates to improvements in chuck pins and has 'for an important object thereof the provision of a pin which may readily be removed from the chopping block. A

In its usual form the chuck pin consists Y in a tapered pin having a hole near the top.

In use the chuck pin is inserted through the piece of meat which it is desired to secure 'in position upon the block, Vand driven into' the wood of the chopping block. When it is desired to remove the same a steel .or similar implement is inserted in the hole or 'the pin rotated until free from the block. As will be obvious, thismanner of releasing the pin has a tendency to enlarge the hole to a size at which the steel no longer is eifectual for rotating the pin and accordingly it becomes necessary to employ a wrench. Furthermore, the .blow struckV upon the upper end of the pin to drive the same into the wood will distort the pin at the point where it is weakened by the hole. In accordance with 'my invention I provide as an article of manufacture, a tapered pin such as is commonly employed, provided with a pivoted handle, the pin and handle having means whereby the movement of the handle is limited when'the handle has reached a de- -sired elevation so that pressure may be eX- erted upon the handle bothto rotate vthe pin and to elevate the same, the handle normally lying substantially parallel to thev pin.

Other objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings,l wherein for the purpose of illustration is shown a preferred embodiment of my invention andl wherein like reference characters designate like parts throughout,

longitudinally and pointedV upon its lowerA end, as at 11, the upperend of thepin Vbeing fairly heavy and being adapted for the reception of a blow from a cleaver or similar implement, whereby lit may be driven into the chopping block.

rIfhe numeral 12 indicates a ony the side of the pin ladjacent the :upper end thereof 'and ,having` 'an opening ..13 formed therein adaptedV for theA reception .of a pivot pin 14. This pivot pin. likewise extends through arms 15V formed 'by the furcation of oneend of. a handle member' 16 to pivotally connect the handle member.

is a sectional view.k vtaken through lug formed 16 to the pin. The handle member 16 isl provided adjacent `its pivot `point with av shoulder 17 adapted to. coact with a stop Y shoulder 18 formed upon the lug 12 to check `the rotary motion of the handle llupon its pivot when the handle is approximately at rightfangles to the pin. The handle normally lies substantially parallel to the pin 10, assuming this kposition bygravity, It'will be noted thatwhen the handle is moved to the elevated position, pressure may be brought to bear upon the pin, there,` -I by not only to rotate the pin but toelevate the same so that the pin may be readily removed' from the chopping block. i

Asmany changes in the shape, size and arrangement of Vthe various parts hereinvshove set forth are possible without depart-f y ing in any manner from the spirit ofniyV invention, I do not ylimit myself to the specific structure lthereof except Vas hereinafter claimed. What I claim is: Y 1. As a new Aarticle of manufacture, a' chuck pin having .a handle pivotally con? nected thereto adjacent the upper end thereof, and means for limiting the pivotal movement of the handle with relationto the pin.'- 2. In an varticle ofmanufacturaa chuck pin having a lug extending outwardly therefrom, a handle pvotallyoonneoted with the lug,a shoulder formed upon said handle, and a stop-shoulder orrnedrupon the lug and with which said handle'engages when said handle is disposed at approximately right angles to said pin.

As a new article of manufacture, a Chuck pin provided upon the upper end thereof with an outstanding' lug' having an opening` formed therein adapted for the reception of a pivot pin, a handle having one end thereof furcated to form spaced arms, said arins likewise being; provided With openings through which the pivotY pin extends. and a shoulder"extending outwardly from said lug` and with which said handle engages to limit the rotation thereof upon
